NanoSizer STERILE: the world's first sterilized and fully assembled liposomes, lipids, and polymers extrusion systems. The fully-assembled feature of these extruders allows researchers to save a significant amount of time of assembly. NanoSizer extruders provide researchers and developers with contamination-free liposome extrusion systems with no need for cleaning harsh biological materials and molecules. The low dead-volume and leak-proof character of these extruders greatly prevent the loss of precious lipid or other nano- or micro- particle solutions. Also, you can make the entire process of extrusion fully automated by NanoSizer AUTO technologies, whether you like to extrude 1mL or 300L. No need for autoclaving or further preparation: just open the sealed sterile kit and start extruding!
